Description

The invention relates to welding production, in particular, to welding o6opyflOBtfii for welding longitudinal seams of shells. A known installation for (Welding a longitudinal seam of a shell using a lead-in and an exit technological strips, comprising a stand with a vertical column, a console mounted on a column, self-propelled a talbzhka with a welding head mounted on the console, a device for forming a seam and a clamping device for pressing the shell and a device for forming a seam to the console t1. The disadvantage of this installation is It is impossible to remove the thread and the output technological strips on it, which are used when welding the longitudinal weld of the shell to improve the quality of welding at the beginning and next to the weld. They are removed after the shell is unloaded on other independent installations, which reduces the productivity of labor and increases the number of processing units. The aim of the invention is to increase productivity by reducing units of processing equipment. This is achieved by the fact that the installation is equipped with a mechanism for cutting off technological strips made in the form of fixed stops for the shell for two fixed knives, two movable knives, as well as mounted on the base of the power cylinder and support rollers, wedge sliders fixed on the rod of the power cylinder and supported on the aforementioned cylinders, and two rods, at one end of which movable knives are mounted, and the other ends mounted to be movable by a center slide. FIG. 1 shows an installation, a general view of FIG. 2 shows the fastening of the movable knives of the mechanism for cutting technological strips; in fig. 3 - fastening the fixed knives of the mechanism, tl technological segments; in fig. 4 is a view along arrow A in FIG. 3

The installation has a frame 1 with a vertical column, on which the console 2 is fixed for directing self-driving; adheitle: ЗШ1С10 with welding head 3, Shell 4, with welded edges laid on the device for forming the seam 5, together with the leading and output technological strips is pressed against the clamping device 6 console 2. The installation is equipped with a mechanism for cutting technological strips. The power cylinder 7, mounted on the frame 1, has movable wedge sliders 8 and 9 at the ends of the rod. The polzun is supported during the working stroke on the support rollers IG and 11, к6Нт Ий | УЮЙТс on the frame 1 by means of axles. 12. In the engagement with wedge sliders through the slots in them are the rollers 13 and 14, mounted on the lower ends of the rods 15 and 16. At the upper ends of the ydov Movable knives 17 and 18 are fixed. The fixed knives 19 are fastened to the frame 1 by means of supporting struts 20 which are fixed in place on the bed.

A fixed stop 21 for cutting one of the technological straps is attached to the left support column 20, which serves simultaneously to fix the stationary knife 19k to the base 1, and the movable stop 22 is attached to the rod 16.

The guide rollers 23, which serve to rotate and translate along them the shell to the stops 21 and 22 when trimming those draw bars, are attached to the frame 1 symmetrically with respect to the knives 18 and 17.

The installation works as follows.

After welding and lowering the device for forming the seam 5, the casing with welded 3 rd and output technological strips is lowered onto the guide rollers 23, rotated by hand 180 ° relative to the longitudinal axis by rotating the casing on the rollers and shifted along the shm to the left until it touches the fixed stop 1 .

When moving the stem of the power cylinder 7 to the left, the wedge slider: 8, resting on the roller 10 through the roller 13, moves the rod 15 with the knife 17 down, while cutting off the technological bar 24, welded to the shell, as the latter is between the fixed knife 19 and the knife 17 in the process of moving it down. Simultaneously with the movement of the rod 15 down, the wedge slider 9 pushes up through the roller 14 the shanks 16 with the knife 18 fixed on it and the movable stop 22 of the shell 4. The shell is cut from the left (the bar moves by hand but directs the rollers 23 to the right until it stops 22. When the power cylinder shaft is moved to the right, the wedge slider 9, resting on the rollers 11, moves the shaft 16 with the knife 18 to the inner end, and the technological bar 25 is cut off analogously to the first friend.

In the case of the stroke of the rod 16 downward by the unloading mechanism by moving to the right, the shell is removed from the installation.

The proposed installation allows you to increase productivity and reduce the number of units of technological equipment.
